尺骨茎突骨折的治疗进展

Progress in treatment for ulnar styloid fractures

桡骨远端骨折常常伴发尺骨茎突骨折，尺骨茎突骨折是否需要治疗一直存有争议。一些研究认为伴发的尺骨茎突骨折不会影响桡骨远端骨折治疗后的解剖学、影像学和腕关节功能结果；而另一些研究则发现尺骨茎突骨折和下尺桡关节不稳定、三角纤维软骨复合体损伤、腕关节活动受限以及握力减少有关。本文针对尺骨茎突骨折的治疗及其影响进行综述。

Ulnar styloid fractures are commonly associated with distal radius fractures. It remains a surgical dilemma whether to fix the ulnar styloid or not. Some surgeons believe that management of the ulnar styloid fractures is imperative while others feel that they should be managed conservatively. Several clinical studies have concluded that the ulnar styloid fractures have no impact on the anatomic, radiographic, or func- tional results when accompanied with a distal radius fracture. Others have found they are associated with distal radioulnar joint （DRUJ） instability, concomitant triangular fibrocartilage complex （TFCC） tear, decreased range of motion, or decreased grip strength in the affected wrist. The purpose of this review was to evaluate the effect of associated ulnar styloid fractures on the distal radius fractures and to discuss the treatment of ulnar styloid fractures.
